Spiders of the National Nature Park Slobozhanskyi (Northeastern Ukraine)

Study Extent

Slobozhanskyi National Nature park, Kharkiv Region, Ukraine

Sampling

In 2013, the lines of 10 pitfall traps at a distance 10 m from each other were established in three habitats, viz. an old pine forest, bank of a small bog in the clear-cut, and bank of a big peat bog in the wood. We used 250 ml plastic caps half filled with 4% formalin. In addition, spiders were sampled by hands and by sweep netting in the forest herbage, riparian vegetation of the small bog, and on the clear-cut in the old pine forest. The material was collected on May 23, June 5, and July 7. The traps were exposed from May 23 to July 7, with an additional check on June 5. In 2019, we investigated burnt and unburnt areas of a peat bog, pine plantation and an old pine forest. On May 23, nine traps were set at each study plot. They were arranged by three at a distance 10 m between the triplets and 3 m between the traps within each triplet. The traps were checked on June 13, July 7, and August 1. Each triplet was preserved separately as a subsample in a sample of nine traps. Geographical locations were indicated by GPS-navigator in decimal degrees according to the WGS 84 system. The nomenclature follows the World Spider Catalogue (WSC, 2022).
